Abstract: Based
on a human visual system (HVS) based approach, digital video
image quality and perceptual coding (DVIQPC) outlines the
principles, metrics an standards associated with perceptual
coding as well as the latest techniques and applications. It
discusses the latest developments in vision research as they
relate to HVS based video and image coding. It discusses
subjective and objective assessment methods, quantitative
quality metrics including vision model based digital video
impairment metrics, test criteria and procedures. It examines
post-filtering and reconstruction issues associated with color
bleeding, blocking, ringing and temporal fluctuation artifacts
in detail along with methods to reduce/eliminate them. It also
focuses on picture quality assessment criteria. It poses new
challenges to vision research and/or how to transfer vision
science to imaging and visual communication systems
engineering. It also poses an obvious theoretical and
practical challenge regarding the concept of psychovisual
redundancy (also how to define this quantitatively) and to
establish theoretical bound for perceptually lossless coding. Brief
Biography of the speaker:
K. R. Rao received the Ph. D. degree in electrical
engineering from The University of New Mexico, Albuquerque in
1966. Since 1966, he has been with the University of Texas at
Arlington where he is currently a professor of electrical
engineering. He, along with two other researchers, introduced
the Discrete Cosine Transform in 1975 which has since become
very popular in digital signal processing. He is the co-author
of the books “Orthogonal Transforms for Digital Signal
Processing” (Springer-Verlag, 1975), Also recorded for the
blind in Braille by the Royal National Institute for the
blind. “Fast Transforms: Analyses and Applications” (Academic
Press, 1982), “Discrete Cosine Transform-Algorithms,
Advantages, Applications” (Academic Press, 1990). He has
edited a benchmark volume, “Discrete Transforms and Their
Applications” (Van Nostrand Reinhold, 1985). He has coedited a
benchmark volume, “Teleconferencing” (Van Nostrand Reinhold,
1985). He is co-author of the books, “Techniques and standards
for Image/Video/Audio Coding” (Prentice Hall) 1996 “Packet
video communications over ATM networks”(Prentice Hall) 2000
and “Multimedia communication systems” (Prentice Hall) 2002.
He has coedited a handbook “ The transform and data
compression handbook,” ( CRC Press, 2001). Digital video image
quality and perceptual coding, (with H.R. Wu),Taylor and
Francis (2006). Introduction to multimedia communications:
applications, middleware, networking, (with Z.S. Bojkovic and
D.A. Milovanovic), Wiley, (2006). He has also published a
book, “ Discrete cosine and sine transforms”, with V. Britanak
and P. YIP (Elsevier 2007). Some of his books have been
translated into Japanese, Chinese, Korean and Russian and also
published as Asian (paperback) editions. He has been an
external examiner for graduate students from Universities in
Australia, Canada, Hong Kong, India, Singapore, Thailand and
Taiwan. He was a visiting professor in several Universities -3
weeks to 7 and1/2 months- (Australia, Japan, Korea, Singapore
and Thailand). He has conducted workshops/tutorials on
video/audio coding/standards worldwide. He has supervised
several students at the Masters (59) and Doctoral (29) levels.
He has published extensively in refereed journals and has been
a consultant to industry, research institutes, law firms and
academia. He is a Fellow of the IEEE. |
